The faster rotation flattened the cloud into a pancake, with the Sun at the center and planets forming within that plane. Planetary systems around other stars tend to form in a similar way.

The James Webb Space Telescope has observed two large planets at different stages of infancy - one with an atmosphere ...

For nearly a quarter of each Uranian year, the Sun shines directly over each pole, plunging the other half of the planet into a 21-year-long, dark winter." Astronomers are interested in how this ...

MAROON-X measures the "radial velocity" — the slight wobble back and forth of Barnard's Star as it revolves around the center of mass shared between itself and the four orbiting planets.

As of 2025, astronomers have identified at least 14 stars within 10 light-years of the Sun ... planets is a smaller sub-Earth, with no more than about a third of Earth’s mass, and travels around ...
